*Target (protein/gene name): Ribosomal RNA Large Subunit Methyltransferase Cfr/ 23S rRNA (adenine2503-C8-methyltransferase)
*NCBI Gene # or RefSeq#: 441771
*Protein ID (NP or XP #) or Wolbachia#: 2.1.1.224
*Organism: Clostridium botulinum (strain Hall / ATCC 3502 / NCTC 13319 / Type A)

Etiologic Risk Group: 2

Disease Information: This bacteria releases a toxin that causes the disease, commonly known as botulism. There are five kinds of botulism infections, all of which can be fatal if not treated immediately: foodborne, wound, infant, adult intestinal, and iatrogenic. It is a rare disease in the United States, with an average of 145 cases per year. The most common forms are foodborne, infant, and wound botulism. Signs and symptoms include vision problems, muscle weakness, slurred speech and mouth dryness and in infants, poor muscle tone is common in those afflicted with the infant form of the infection. Botulism is prevented through proper food production and cooking methods. It can be treated with an emergency anti-toxin if an infection occurs.
